Stop device for left &amp; right hand sliding doors

ABSTRACT

A stop device for sliding doors or windows is described, wherein the device has a block member secured to the lower end of the sliding door so that the block member forms an appendage to the door and lying substantially within the plane of the door. The block member is formed symmetrical about a horizontal plane so that it can be used with either right or left-hand sliding doors, and has a vertical bore wherein a bolt or pin is disposed. Communicating with the bore is a horizontally disposed hole lying substantially on the horizontal plane. Within the hole is an inwardly biased steel ball. The bolt has two axially spaced circumferential grooves that are singularly engaged by the steel ball to provide predetermined stops for the bolt. The bolt can be inserted within the bore from either end.

5 Claims, 3 Drawing Figures STOP DEVICE FOR LEFT & RIGHT HAND SLIDING DOORS FIELD OF INVENTION This invention relates to a stop device for a sliding door or window, which stop device can be used with left or right-hand sliding doors.

BACKGROUND OF THE INVENTION Stop devices for sliding doors are generally made for either a left-hand sliding door or a right-hand sliding door. The stop devices which are designed to be used with either type sliding door, up to now, have been more expensive than the single use type.

OBJECTS OF THE INVENTION These and other objects and features of advantages will become more readily evident after studying the following detailed description and the appended drawing of the preferred embodiment of the invention.

BRIEF DESCRIPTION OF THE DRAWING FIG. 1 is an elevation of a lower corner of a sliding door and, in this case, the left corner, showing my novel stop device secured thereto.

FIG. 2 is a section taken on line 2-2 of FIG. 1 in the direction of the arrows.

FIG. 3 is a section taken on line 3-3 of FIG. 1 in the direction of the arrows.

DETAILED DESCRIPTION OF THE INVENTION Referring to FIG. I in particular, my novel stop device is shown secured to the lower left-hand corner of a sliding door or window 11 that opens by sliding to the left as viewed. In this disclosure door will represent either a door or window. The door is mounted on a slide base 16. As will become more apparent hereinafter, the device 10 can also be secured to the lower right-hand corner of a sliding door that opens by sliding to the right, or in the opposite direction. The device 10 includes a block 12, having a flange 13 as shown in FIG. 3. Block 12 is secured by the flange 13 to the door 1 l by suitable screws 14. The block 12 is provided with a semi-cylindrical slot 18 on its lower surface, as shown in FIG. 2, to allow the block 12 and door 11 to move freely along a track rail 21 that is disposed on the top of the slide base 16. A vertical bore 26 is formed within the block 12, extending from the top surface to the bottom surface thereof. A horizontal hole 27 is drilled through from the front surface to communicate with the bore 26. As one observes, the hole 27 is not drilled completely through but untill there is formed an opening 28 with the bore 26, which opening 28 is smaller than the diameter of the hole 27. The hole 27 is tapped, as shown, to form threads for a set screw 29. Under the set screw is placed a steel ball 31 and resilient disk 32, made of, for example, NEOPRENE, so that the ball 21 is spring biased toward the opening 28. The diameter of the ball 31 is greater than the opening 28 to retain the ball 31 within the bore 27. Within vertical bore 21 is disposed a bolt or pin 41 that has two axially spaced circumferential grooves 42 and 43 (FIG. 2). The pin 41, when in its lower position, engages one of the bores 45 in base 16 and the ball 31 falls into the top groove 42, as shown, to provide a stop for the pin 41 to prevent it from falling further into the ball 45. When one raises the bolt 41, by hand, out of the bore 45, groove 43 is so spaced that the ball 31 engages it when the lower end of the pin 41 clears the bore 45. The pin 41 is again prevented from falling. The neoprene disk 32, which is about one/sixteenth of an inch thick, provides sufficient resilience to allow the ball to retract when one raises or lowers the pin 41.

To make the same stop device 10 useful with doors opening in the opposite direction, the horizontal hole 27 is disposed substantially midway between the top and bottom surfaces of block 12. The top surface is also provided with a semi-cylindrical groove 51 to clear a rail similar to rail 21. The spacing between grooves 42 and 43 is such that when one groove 42 engages the ball 31, the other groove 3 is disposed near the lower surface of the block. The length of the pin 41 below groove 43 is such that when groove 43 engages ball 31, the pin 41 clears the bore 45. To use the stop device 10 with doors that open in the opposite direction than as shown, one need only remove pin 41 and reinsert it from the opposite side into the vertical bore 26. The block 12 is also provided with another semi-cylindrical groove 52 on the surface adjacent to door 11, as shown in FIG. 3, to clear any obstruction that one may find at the bottom of the door near the rail.

Although one embodiment of my invention has been shown, the invention is not limited thereto. One skilled in the art, after studying the above description could readily visualize other embodiments. Therefore my invention is not limited to the described embodiment, but includes all embodiments falling within the scope of the following claims.
